Kicking off the weekend a little early, Julianne Hough hit up the Kaleidoscope Ball at the Beverly Hills Hotel last night (April 10).

Joined by her brother Derek Hough (in a Ted Baker London suit) and Maria Menounos, the “Rock of Ages” hottie was all smiles as she posed for a few quick photos on her way into the soiree.

Julianne told ABC News that while she’s looking forward to being a part of the 40-city “Dancing With The Stars” North American Tour, she knows it’s going to be grueling.

"I'm already freaking out. We are going to be on stage for 90 minutes. It's not just like a light jog. We are going to be doing all sorts of styles of dance, and we are going to be singing and interacting with the crowd and the audience."

She added, "We want this to feel like the biggest rock concert you've ever been to, but for dance.

All I know is I am going to have a very fit, rocking body by the end of this tour. I'll be putting my bikini on, for sure."
